hi sparks, I do agree that most students these days has no social values.. talk loudly, inconsiderate, etc
But I do think it is due to parental guidance as I had seen parents do not impart good social values into their children. If one parent imparts correctly (child receives) but upon reaching school, after seeing everybody doing otherwise, mindset and habits will change from good to bad.
Thus, I hope to see myself imparting good social values and kick those bad habits as children will follow parent's behaviour. Hope I will not be too stressed out by it.
**disclaimer: the above does not apply to all parents and children. It's just my personal opinion.
